data方法的问题

@wendal
data方法

    /**

     * @param linkname 关联查询
     * @return
     */
    public NutMap data(int length, int start, int draw, List<DataTableOrder> orders, List<DataTableColumn> columns, Cnd cnd, String linkname) {
        NutMap re = new NutMap();
        if (orders != null && orders.size() > 0) {
            for (DataTableOrder order : orders) {
                DataTableColumn col = columns.get(order.getColumn());
                cnd.orderBy(Sqls.escapeSqlFieldValue(col.getData()).toString(), order.getDir());

@tonyyule 422是哪一行

@wendal 

for (DataTableOrder order : orders) {

看来order里面实际存储的并非DataTableOrder,二而是Integer

@Param("::order") List<DataTableOrder> order

看你datatables js怎么写的

@Wizzercn 页面家了一个订单状态的查询条件 @Param("::order") List order 莫名其妙就有值了

        <div class="btn-group tool-button col-lg-1">
            <select id="order_state" name="order_state"class="navbar-btn form-control">
                <option selected value="">订单状态</option>
                <option value="1">待付款</option>
                <option value="2">已付款</option>
                <option value="3">待发货</option>
            </select>
        </div>

@tonyyule 因为名字是order开头了啊，符合所标注的前缀表单了

@wendal
页面改了值 就好了

        <div class="btn-group tool-button col-lg-1">
            <select id="ord_state" name="ord_state"class="navbar-btn form-control">
                <option selected value="">订单状态</option>
                <option value="1">待付款</option>
                <option value="2">已付款</option>
                <option value="3">待发货</option>
            </select>
        </div>
